Finding reliable internet in Japan can sometimes be tricky (yeah, I know, sounds odd given how we’re always told how technologically advanced the country is), and sometimes, that lack of reliable connectivity can break a trip, rather than make it. If you’re trying to navigate busy train stations, use translation apps, or hunt down your next accessible destination via the Accessible Japan website, you’re going to need internet access at all times.
One of the simplest and most cost-effective ways to stay online? Picking up a local SIM card. But with so many options out there, how do you know which SIM card is right for your travel needs?
This guide breaks it down by travel style — whether you’re planning in advance, prefer to shop local, or just want the easiest setup possible.
Which SIM Suits Your Travel Style?
Mobal
If you’re a traveler who likes to be prepared well in advance, I’d recommend going with an option like Mobal. They offer worldwide shipping, so you can receive your SIM at home, before you even head to the airport, and their SIMs are super reliable! What’s more, they also support charity, so you can feel good about your purchase in more ways than one!
Recap on why you should choose Mobal?
- Ships anywhere in the world
- Physical SIM or eSIM (no waiting)
- Supports tethering/hotspot
- Proceeds go to education projects in Africa
- English-speaking customer support
For 2025, the available plans include 5GB for ¥2,990, 10GB for ¥3,990, 30GB for ¥5,990, and 50GB for ¥9,990.
Sakura Mobile
If you’re an on-the-go kind of person and you don’t mind shopping local once you arrive in Japan, then I would recommend Sakura Mobile due to their flexible plans. You don’t even need to travel that far once in Japan, with many options for easy pick-up at airports.
Recap on why you should choose Sakura Mobile:
- Airport pickup or hotel delivery
- Uses NTT Docomo’s robust network
- No activation fees
- English-language website and support
For 2025, the available plans are 3GB for 8 days at ¥3,480, 8GB for 15 days at ¥4,980, and 25GB for 30 days at ¥7,480.
IlJmio / b-mobile
Finally, if you’re the kind of person who is conscious of their budget and wants to avoid overspending wherever possible, then I would most likely recommend either IIJmio or b-mobile. Not only are these types of SIM almost always very cheap, but they can also be picked up from various stores, really easily.
What to know:
- Available at BIC Camera, Yodobashi, Don Quijote, etc.
- Bring your passport to purchase
- Setup may require basic Japanese or staff assistance
- Data-only SIMs (no calls/texts)
Estimated pricing is approximately ¥2,000 for around 3GB and ¥3,000 to ¥4,000 for around 10GB. These options are best suited for last-minute planners or seasoned travelers comfortable with a bit of DIY.
Accessibility Considerations
SIM cards offer an affordable way to stay connected with a wide variety of phones. However, the small cards require a small pin and a fair bit of dexterity to change. When it comes to accessibility, if your phone is compatible, eSIMs can be a better option as they eliminate the need to physically handle a SIM card – a real plus for travelers with limited dexterity. If you rely on screen readers or translation tools, you’ll appreciate the English support offered by providers like Mobal and Sakura Mobile. And if you’re traveling with multiple assistive devices, a pocket Wi-Fi might actually be the better choice.
Summing things up!
Staying connected in Japan doesn’t have to be complicated – it just depends on your travel style. If you like to plan ahead and want peace of mind before you even leave home, Mobal is a solid, reliable choice with global shipping, English support, and the added bonus of giving back to charity. Prefer to grab a SIM once you land? Sakura Mobile offers easy airport pick-up and flexible plans with no activation fees. And if you’re more budget-conscious or don’t mind a bit of DIY, options like IIJmio or b-mobile are widely available and very affordable. Just keep in mind your accessibility needs – eSIMs are great for those with limited dexterity, while pocket Wi-Fi might be the better fit if you’re traveling with several assistive devices. No matter your style, there’s a SIM card that can keep you connected and stress-free throughout your trip.
